Total ion emission current and purity of ion emission of Cs+ ions for these two forms of aluminosilicates were studied and compared at four different material surface temperatures over 50 h of continuous heating. In addition, the ion emission characteristics were investigated for three other compositions of cesium aluminosilicates. It was revealed that as a Cs + ion source, β-eucryptite gives the optimum ion emission at the temperature of 1100°C. © 1994 American Institute of Physics.||Source Title:||Review of Scientific Instruments||URI:||http://scholarbank.nus.edu.sg/handle/10635/95748||ISSN:||00346748||DOI:||10.1063/1.1144498|
